The suspect, 18-year-old Eh Lar Doh Htoo, is charged with assault with a deadly weapon with intent to kill, and other charges are expected. Htoo knew the victims but they weren't related, New Bern police Lt. Ronda Allen said. A language barrier was affecting the investigation, she said.
Police did not release the names of the victims or any possible motive.
Htoo was expected to appear in court on Thursday. Police said they did not know whether Htoo had an attorney yet.
About 11 p.m. Tuesday, officers were called to a report of a person with a knife, Allen said. The officers entered the home and found the injured and two of the dead children. A third child died at a hospital, Allen said.
The wounded were another juvenile and an adult, Allen said. They were treated and released from a hospital.
New Bern is a picturesque town of 30,000 on the water near the coast and is home to about 1,900 Burmese refugees.
Susan Husson, executive director of the Interfaith Refugee Ministry in New Bern, said the victims' family and the suspect's family likely came through her office before settling in New Bern, but she didn't know them personally.
She said the first Burmese refugee came to New Bern around 1999.
"It's just really hard right now," she said. "It's been really horrific."
New Bern draws tourists from around the region and is known for being the birthplace of Pepsi and the colonial capital of North Carolina.
